I'll have to assume that you are talking about the USB support not working with this new version. I have it installed on Fedora and run XP virtualized (VirtualBox 1.6.2). I have USB access to my printer/scanner, ipod, and memory sticks. It was a bit confusing to get it working--out of the box you won't have access if you are running it as a normal user. This is due to the ownership or the USB devices on Linux. You need to head over to the device folder and make sure to set group ownership to the vboxuser. You also need to add an entry to the fstab to set the devgid on new USB mounts. Check the forums on the VirtualBox site. There are some FAQs on getting USB enabled.
